A comprehensive set of functions providing frequentist methods for network meta-analysis:

• frequentist network meta-analysis (Rücker, 2012; Rücker & Schwarzer, 2014);

• net heat plot and design-based decomposition of Cochran's Q (Krahn et al., 2013);

• measures characterizing the flow of evidence between two treatments (König et al., 2013);

• ranking of treatments based on frequentist analogue of SUCRA (Rücker & Schwarzer, 2015);

• partial order of treatment rankings ('poset') and Hasse diagram for 'poset' (Carlsen & Bruggemann, 2014; Rücker & Schwarzer, 2017);

• split direct and indirect evidence to check consistency (Dias et al., 2010);

• league table with network meta-analysis results;

• additive network meta-analysis for combinations of treatments (Rücker et al., 2020);

• network meta-analysis of binary data using the Mantel-Haenszel method or the non-central hypergeometric distribution (Efthimiou et al., 2019);

• 'comparison-adjusted' funnel plot (Chaimani & Salanti, 2012);

• automated drawing of network graphs (Rücker & Schwarzer, 2016);

• rankograms and ranking by Surface Under the Cumulative RAnking curve (SUCRA) values;

• contribution matrix (Papakonstantinou et al., 2018; Davies et al., 2021 )
